9 Claims.

This invention relates to window construction and more particularlyrelates to double hung or sliding type windows.

One of the objects of the invention is to provide new and improved typesof double hung windows having improved weather stripping to secureabsolute tightness from the weather, and at the same time insure easysliding operation.

It is a further object of the invention to provide a. double hung windowconstruction in which the mounting of the sashes will allow for lateralmovement, permitting removing of the sash without requiring removal ordisplacement of any part of the jambs.

It is a further object of the invention to pro vide an improved mullionconstruction for multiple windows.

Other objects and advantages of the invention will appear from thefollowing description of certain preferred embodiments of the inventionchosen to illustrate the principles thereof.

In the accompanying drawings:

Figure 1 is a fragmentary front elevation of a multiple window embodyingthe invention;

Figure 2 is a vertical section on line 2-2 of Figure 1;

Figure 3 is a horizontal section on line 3-3 of Figure 1;

Figure 4 is a vertical section of a window showing a modified form ofthe invention;

Figure 5 is a horizontal section of a window showing a jamb applicableto either the forms of Figure 2 or Figure 4 and showing sashes of thetype shown in Figure 4; and

Figure 6 is a horizontal section of another modified form of sash andjamb, the form of jamb shown being also applicable to receive sashes ofthe form shown in either Figure 2 or Figure 4.

Referring to the drawings in detail and particularly Figures 1 through3, the window frame shown comprises a header I 0, sill II and jambs 12.The header l0 includes a channel-shaped member having upwardly extendingflanges I3 and It at its inner and outer edges, the flange I3 being onthe inside of the window, and bein the shorter of the two. Intermediatethese flanges is a downwardly extending rib I5, and extending downwardlyfrom the outer edge of the header and preferably in the same plane asthe flange I4 is a flange I 6 which terminates in an inwardly turnedportion I1 and acts as a weather guard for the upper portion of thewindow. The upper sash rail is arranged to engage with the header andincludes a hollow extruded portion 20 having pane the flange 2| on theinner side thereof, and the undercut flange 22 on the outer sidethereof,

. which is arranged to key with the putty. If desired, pane clips 23 maybe used throughout the glazing to improve the stability of the windowpane 24.

Extending upwardly from the hollow member are the header engagingflanges 25 and 26 having lugs 21 and 28 respectively mounted on theirinner sides.

Mounted upon the top horizontal wall 28 of the hollow rail member 20 andsecured beneath the lugs 21 and 28 is a triangular shaped resilientnon-corrosive sheet metal weather strip, the legs of the weather strip30 and 3| terminating in outwardly turned edges 32. It will be seen thatwhen the window is thrust into its highest upward position the flanges25 and 26 will engage the face of the header l0 and the downwardlyextending rib IE will enter between the legs 30 and 3| of the weatherstrip. Sufficient spring pressure is provided in the weather strip toinsure a tight weather proof sealing on either side of the rib IS. Theedges 32 are flared sufliciently to permit the rib l5 to enter betweenthem, but are preferably curved no more than is required for thispurpose and should not for instance be headed over. Thus thelongitudinal flexibility of the edges is largely preserved and a bettersealing contact is obtained throughout the length of the rib I5 thanwould be the case if the edges were so formed as to have longitudinalrigidity. The top rail member 20 of the upper sash is preferably formedwith an inwardly projecting flange 33 constituting a continuous sashpull. The flange also serves the additional function of reinforcing thetop rail member since it changes the center of gravity of the rail andrelieves the intensity of direct stresses and strains on the rail.

The meeting rail assembly comprises the upper and lower hollow extrudedrails 35 and 36, respectively. The upper meeting rail 35 includes aninwardly extending flange 31 having an upwardly extending web 38 nearthe inner end thereof terminating in the bevelled edge 39. The lowermeeting rail includes an outwardly extending flange l0 terminating in adownwardly extending web 4| having a bevelled edge 42 adapted to engagewith the bevelled edge 39 when the window is closed. The rail 36 has anoutwardly extending flange 43 terminating in an upwardly turned lip 44the bottom of which engages the flange 31 on the top thereof when thewindow is closed. The lower flange l3 forms with the upper flange acarrying members on one side thereof including pocket in which aV-shaped resilient metal weather strip is mounted having a base 41, avertex 48 held behind the lip 44 and a freely movable tongue portion 49held from unlimited movement when the window is in open position by theweb 4i and engaged in tight sealing relation with the upper meeting railby the web 38 when the window is closed.

As shown in Figure 2 the sill comprises a single metallic extrudedportion having an apron 50 and a step portion 5! and terminating at itsinner side in upwardly sloped portion 52 having a downwardly extendingflange 53 which can be secured to or supported upon the wall structure.The sloped portion 52 is particularly adapted to receive condensationfrom the inside of the window and to direct it off harmlessly to theoutside of the building.

The lower sash rail which engages the sill includes the inner wall 55having a lower web 56, a downwardly extending flange 51 terminating inan outwardly turned lip 62. The flange 5] engages directly with the stepportion of the sill when the window is closed and a downwardly extendedouter flange 58 having an inwardly turned flange 59 which engages theriser 60 of the step portion of the sill when the window is in closedposition.

To insure absolute tightness of the window with the sill a V-shapedmetallic weather strip member is provided having a base 6| which engagesthe bottom web 56 of the rail. The vertex 55 of the V is held under theoutwardly turned lip 62. The other arm 66 of the V is a freely movabletongue held from unlimited movement when the window is open by theflange 59 and engaged by the top of the step portion 60 of the sill whenthe window is closed.

The sill also includes a downwardly extending flange I at its outerextremity beneath which a caulking pocket iI may be provided and alsohas an intermediate leg I2 which rests on the masonry, supporting thesill and providing a back for the caulking pocket.

Referring to Figure 3 the jamb I2 is shown as a channel shaped memberhaving outwardly extending inner and outer flanges I5 and I6 terminatingin inwardly and outwardly extending portions 11 and 18 which are adaptedto key with the masonry. The jamb also includes the 'part ing strip 19formed therein and on the inner and outer side thereof, flanges 80 and8| having outwardly and inwardly extending stop beads 82 and 83respectively. Intermediate each of the flanges 80 and III and theparting strip are situated the guide ribs 85 and 96 respectively forengagement with the sash rail in the manner to be described.

The sash rail of the inner sash includes the web 90 having the paneengaging portions on one side thereof similar to those described inconnection with the top rail, and having an inner flange 9I extendingfrom the inner side of the web. The flange 92 terminates in an outwardlyturned lip 93 which bears against the parting strip 19 and provides firmsealing contact between rigid members. The flanges 9I and 92 will be inreverse position on the opposite side of the parting strip as shown bythe partially removed sash in the lower portion of Figure 2. Each of theflanges 9I and 92 contains on its inner side the ridges 95 and 96 andoutwardly of said ridges the undercut ribs 91 and 98. Mounted betweenthe flanges SI and 92 is a triangular shaped metallic weather striphaving the two base angles of the triangle held respectively between theridge 95 on either side of the guide ribs and 86 in sealing slidingrelationship.

It will be observed that considerable lateral movement of the sashbetween the jamb membersis possible and as shown in the lower part ofFig ure 3 the sash may be removed by sliding it toward one jamb whichwill cause disengagement of the legs of the weather strip at theopposite side of the sash from the flange on the opposite Jamb and alsocarry the flanges 9| and 92 clear of the stop bead 93 whereby the sashmay be removed.

Where it-is desired to mount a series of multiple windows a mullion I05may conveniently be provided by combining two of the heretoforedescribed jamb members I2 as shown in Figure 3.

The two jamb members forming the mullion may be secured together by anyconvenient means, but we have found it convenient to use a channelmember, having a base I06 and flanges I01 and I08 which form the sidesof the channel having a further flange I09 extending in the samedirection between said flanges I01 and I08. The flange I09 extendsbetween the outwardly extending flanges of the two jamb members H0 andIII which are comparable to the outwardly extending flange I8 of thejamb I2, and terminates in the holding portion I I2 which may take anyconvenient form. The channel member which holds the two jambs in placeas a mullion may be conveniently fashioned by extruding in one piece.

Referring now to Figures 4 and 5 the modification of the invention shownin these figures includes a header member of rolled sheet metal I20preferably of non-ferrous or non-corrosive metal which is folded betweenits ends to provide a rib I2I for engagement with the top rail of theupper sash and formed at its edge toward the outside of the window witha flange I22 terminating in an inwardly directed lip I23. The headermember I20 may be mounted upon and reinforced by an angle plate I25which may be of iron or non-ferrous metal and which is preferablyprovided with an inner flange I26 and with a wide outer flange I21 whichmay be imbedded in the masonry or attached to lintel I28 in any suitablemanner as by screws or rivets I29. The angle plate I25 may, if desired,be spaced from lintel I28 so as to provide a pocket for caulkingmaterial I30.

The sill of the window may be of any suitable form. For instance, asshown in Figure 4, it comprises a plate of non-ferrous or non-corrosivemetal having an inclined apron I32 which terminates at its forward edgein a downwardly projecting flange I33. Near its inner edge the sill hasa folded rib I34 for engagement with the bottom rail of the lower sash.This non-corrosive metal sill plate is preferably supported andreinforced by a flanged plate I35 and braces I36, which may be made ofiron or of non-corrosive metal as desired.

The window jambs are preferably of the form shown in Figure 5 and eachcomprises a channel member I40 preferably made of non-ferrous ornon-corrosive metal, said channel being provided with an inner flangeI4I having a lip I42, and with an outer flange I43 having a lip I44.Substantially centrally of the bottom of channel I40 an inwardlyprojecting rib I45 is provided, and fitted over this and secured in anysuitable manner, as by screws I41, is a channel shaped parting stripI48. A pair of sash receiving channels is thus provided. Formed in thebottom of each of these sash receiving channels is an inwardlyprojecting sash guide rib I50 which is preferably of considerable widthso that it projects well out from the bottom of the main channel memberI40, and nearly as far as the lips I42 and I 44.

For reinfohcing the jam channel I40, a reinforcing plate I55 ispreferably provided which is secured to the back of the channel I40 inany suitable manner, as by welding or by means of screws or rivets, andwhich comprises an angle web I56 and a flange I51, the latter beingpreferably parallel to the plane of the window. Braces I58, which may bepunched out of web I56, connect the flange I51 with the back of the jambnear the flange I43 so as to hold the angle web I56 rigidly spaced fromthe channel at th proper angle. A very strong construction is thusprovided which renders the jamb rigid and is adapted to interlock andbond the masonry.

The sashes comprise stiles which may be extruded from aluminum, orbronze or other suitable metal, each stile having a base I60 suitablyformed to hold a pane of glass and carrying an inside flange I6Iterminating in a lip I62 and an outside flange I63 having a lip I64.Inwardly projecting from the flanges I6I and I63 are intermediate ribsI66 which are located at a distance from the base I60 of the sash stile.Mounted between the flanges I6 I and I63 in the space defined betweenthe lips and ribs on the flanges is a resilient metal sash guiding andsealing strip which may desirably be formed of non-corrosive metal suchas bronze or stainless steel, and which comprises a transverse base I10supported on the ribs.

I66, side flanges I1I extending from the base to just below the lips I62and I64 and inwardly directed resilient tongues I12 which are adapted tobear against the sash guiding rib I50 with sufficient pressure to form aweather tight seal. The faces of the sash stiles adjacent to the partingstrip I48 normally bear against the parting strip so as to form closemetal to metal contact, and the seal thus effected, in addition to theseals effected by engagement of the tongues I12 with the guide rib I50,form a triple barrier against the weather. The sash, however, being heldin position only by engagement with the resilient tongues, cannot bind,jam or rattle. The construction described permits removal of a sasheither by sliding the resilient sealing member endwise out of its recessin the sash stile, or if desired, the sash may be taken out withoutremoving any part by simply forcing the sash laterally in the plane ofthe glass to an extent sufiicient-to permit one stile of the sash toclear the lip I42 past the edge of the guide rib I 50, whereupon thesash may be removed. Owing to the space between the base I60 of the sashstile channel and the base I 10 of the guiding and sealing member, thelatter can be sprung sufliciently to permit the necessary lateralmovement of the sash, as clearly shown at the lower part of Figure 5.

The top rail of the upper sash comprises a hollow extruded section,preferably having a partition I13 across the same which supports aresilient metal weather sealing member similar to that used in thestiles of the sash, and which is adapted to engage the rib I2I. When thesash is moved down so that the tongues I12 leave contact with the rib,the edges of the tongues spring together, thus closing the space in thechannel below them against the entrance of dirt. The bottom rail of thelower sash is preferably of similar section to the top rail of the uppersash and carries a similar weather sealing member which engases with therib I34.

The meeting rail of the lower sash is preferably formed to provide alaterally projecting channel member I14 which is adapted to hold aweather sealing member of the same shape as those used elsewhere in thesashes. This meeting rail is also provided with a laterally projectingnarrow flange I15. The meeting rail of the upper sash is provided with alaterally projecting flange I16 adapted to engage under the flange I 15when the meeting rails meet, the flange I16 carrying an upwardlyprojecting rib I11 adapted to project between the tongues I12 of thesealing member so that a three point seal is provided at the meetingrails. The channel I14 and resilient sealing member are preferablycarried on the meeting rail of the lower sash as shown, so that theywill face downwardly and will not collect water and the springingtogether of the edges of the tongues I12 when the rib I" is withdrawnfrom contact therewith by the opening of the window also helps toexclude dust, etc. It will be seen that the sealing members may be oflike cross section throughout and that they are held in position on thesash members by the flanges of the sash, thereby dispensing with the useof screws or other fastening means. The weather sealing means may alsobe removed without dismounting any part of the frame or destroying thesealing means themselves.

In Figure 6 a further modification of the window of this invention isshown in which each jamb is formed of a channel I at each edge of whichis a flange I8I terminating in a lip I82. The central part of thechannel is off-set as indicated at I83 and the sashes are guided by twoguide ribs I84 connected by a web I85. The member comprising the ribsand web is removably secured in place in any suitable manner as byscrews I61, and is divided horizontally near the center of the windowinto two parts to facilitate removal. The removal of the guide ribmembers permits removal of the sashes and also provides access to thecounterbalancing means indicated at I88. The sash stiles are of channelform and each comprises a base I carrying glass and putty retainingmeans and inner and outer flanges I9I and I92 which have lips I93 attheir edges and lugs I94 placed a short distance from the base I90. Sashsealing and guiding members of resilient material are mounted in thestiles and in the form shown comprise a curved base I 95 adapted tocontact with the inner end of a guide rib I84 and two inwardly bowedtongues I96 adapted to engage the sides of the guide rib. Relativelyacute bends 200 connect the tongues with the curved base I95, thesebends interlocking beneath the lugs I94 and the edges of the tonguesbeing retained behind the lips I93. The sash guiding members are thusfirmly retained in the sash stiles, In this construction it is seen thatthere are three points of sealing engagement between the sealing andguiding members and the sash guide rib, namely the two contacts betweenthe sides of the rib and the tongues and the one contact between the endof the rib and the center of base I95. All of these contacts are weathertight but yielding so that the sash floats freely and slides easilywithout binding or Jamming.

For reinforcing the jamb members of the frame and assisting in securingthe frame in the wall, a reinforcing member of the form shown in Figure6 may be employed. This member comprises a flange 220 adapted to besecured to the jamb channel I80 in any suitable manner, as by beingfitted under tongues 22I bent out from the back of the oifset portionI03 of the channel member I80. Adjacent to the flange 220 thereinforcing member has a shoulder 225 which seats against the end of theoffset portion I83. The reinforcing member has an inclined web 221 whichis preferably inclined at a considerable angle to the plane in the backof the jamb channel. The inclined web 221 preferably carries a web 228parallel to the plane of the window, this web being of any desired widthto give the necessary strength and for engagement with the masonry. Theinclined web 221 is preferably braced in position by means of braces 230formed integral with or attached to the web 228 and secured to theflange I8I of the jamb I80, by suitable means such as screws or rivets232.
